Problem Which Popsicle sticks Bridge Design is stronger and can hold more wei bridges. We had to follow the directions. We used popsicle Sticks and hot glue, and after words we went out and tested them. It turned out that mine had held the most weight. I was wondering if it would do it again and why. We also got fore extra sticks to put anywhere we wanted. Background Information ·A bridge is a structure built to span a valley, road, water or other physical obstacle, for the purpose of providing passage over water ·There are six main types of bridges: beam bridges, cables-stayed bridges and truss bridges. ·There are tension and compression on bridges. · Hypothesis I predict that the bridge with the six extra sticks will hold more than the one without the six extra sticks.
